Harnessing Microbial Power: The Sustainable Solution to Septic Tank Treatment

Updated: Nov 21, 2023


microbial treatment of septic tanks

Septic tanks are essential components of wastewater treatment systems for homes and buildings that are not connected to municipal sewers. They play a crucial role in breaking down organic matter and preventing harmful pathogens from entering the environment. However, traditional septic tank treatment methods often rely on harsh chemicals that can harm the environment and pose health risks.

In this blog, we'll explore the microbial treatment for septic tanks, understanding the science behind it, its benefits, and the positive impact it can have on our communities and ecosystems.


The Challenge of Traditional Septic Tank Treatment

Conventional septic tank treatment methods often involve the use of chemical additives to break down organic matter and eliminate odors. These chemicals can disrupt the delicate balance of microorganisms within the septic tank, leading to reduced treatment efficiency and potential environmental damage. Moreover, improper handling and disposal of these chemicals can pose health risks to humans and animals.


Understanding Microbial Treatment

At the heart of microbial treatment for septic tanks lies the use of beneficial microorganisms. These tiny organisms, including bacteria and enzymes, play a pivotal role in breaking down organic matter present in sewage. Unlike chemical-based alternatives, microbial treatment harnesses the power of nature to accelerate the natural decomposition process, turning waste into harmless byproducts.


How Microbial Treatment Works

  • Initiating the Process

Microbial additives, often in the form of powders or tablets, are introduced into the septic tank. These additives consist of specially selected bacteria strains that thrive on organic waste. These additives can be added directly into the tank or through the toilets which eventually reaches the septic tank by gravity.

  • Breaking Down Organic Matter

The introduced bacteria target and digest organic materials present in the sewage. This includes fats, oils, grease, and other solid waste, effectively reducing the overall volume of sludge in the tank. This reduction in the sludge volume reduces the frequency of septic tank cleaning and tackles the odor problems as well.

  • Enhancing Effluent Quality

As the microorganisms work their magic, the effluent produced undergoes a transformation. It becomes clearer and less odorous, signifying a reduction in harmful pathogens and pollutants.


Benefits of Microbial Septic Tank Treatment

  • Environmental Friendliness: Microbial treatment aligns with sustainable practices, as it relies on natural processes and reduces the need for harsh chemicals that can harm the environment.

  • Extended System Lifespan: Regular microbial treatment can prevent the accumulation of sludge and scum in the septic tank, prolonging the system's lifespan and reducing the frequency of pump-outs.

  • Cost-Effectiveness: Investing in microbial treatment can lead to long-term cost savings by minimizing maintenance expenses and avoiding the need for extensive repairs or replacements.

  • Improved Effluent Quality: The treated effluent is of higher quality, making it safer for soil absorption systems and reducing the risk of groundwater contamination.


When dosing the septic tank with microbes, it is important to consider factors such as the size and type of the septic tank, the volume of wastewater (depending on the number of users), and the desired level of treatment.


Sewage Care Anaerobic by Ekam Eco Solutions is a high potency, bacteria-powered formulation specifically designed for use in anaerobic conditions like that in Septic Tanks. Sewage care anaerobic contains a specially isolated blend of microorganisms, micro/macronutrients, and surface tension suppressants.

Sewage care anaerobic helps keep the Sump tanks, Septic Systems, and Sewage Pits trouble-free.

  • It reduces backflow and pumping

  • Reduces 95 - 99 % of odor coming out of septic tanks

  • It removes surface scum more than 80 %

  • Reduces the bottom solids by 50 %

  • It degrades the fats, oils, grease, Starches, Proteins, Animal Fats, Triglycerides, Foaming Surfactants, Soap and phenols

  • It reduces the BOD, COD, and TSS

By harnessing the power of naturally occurring microorganisms, these systems promote efficient decomposition of organic matter, reduce environmental impact, and contribute to a healthier ecosystem. As we move towards a more sustainable future, microbial-based septic tank treatment can play a significant role in improving wastewater treatment practices worldwide.
